Alex Boye released a new video Wednesday highlighting statistics reported by the Bill and Melinda Gates Foundation showing a decline in child mortality rates.

The video is an Africanized cover of Justin Bieber’s “Baby,” and features mothers holding their newborn babies accompanied by statistics about malnutrition, disease and other concerns.

The video was released in collaboration with the Gates Annual Letter, a collection of statistics relating to poverty levels and world health from the Gates Foundation.

“More children survived in 2015 than in 2014,” Bill Gates writes in the letter. “More survived in 2014 than in 2013, and so on. If you add it all up, 122 million children under age five have been saved over the past 25 years. These are children who would have died if mortality rates had stayed where they were in 1990.”

Although these numbers are encouraging, the Gates emphasize that the world still has a long way to go. The intro to the Gates Letter reads, “We hope this story will remind everyone why foreign aid should remain a priority—because by lifting up the poorest, we express the highest values of our nations. One of the greatest of those values is the belief that the best investment any of us can ever make is in the lives of others.”
